I bought this DI for 2 reasons: To ensure a quality balanced out for my synthesizer and for ease of use.
It's like setting up an expensive, 3D, surround home cinema system in your bathroom, it's a waist of potential.
So with that mindset it's a waist of potential to invest in a amazing sounding tool and then let the signal go trough a potato.
This baby ensures me of dual-mono out's that are produced together and of high quality build.
They are rather pricey so I would still suggest to look for cheaper DI's or two mono DI's but invest in these if you can make it part of your budget.
The build quality is very good and you can guarantee recording a sound as beautiful as the signal source it originates from, which for me was one of the reasons I invested in it.
Very happy with this purchase! Thank you Radial Engineering and Thomann!

When using with synthesizers, (even though it's sonic enhancing, tone softening qualities of the Jensen Transformers are often overlooked or unnecessary for modern synths) keep in mind your outputs become balanced XLRs.
Most synthesizers have unbalanced jacks that you can feed into XLR/TRS inputs on your interface and sending phantom power will not normally harm your synth.
In this case however, extra care must be taken to not damage your equipment because phantom power can effectively be send over the balanced XLRs into your synth and cause harm.
